Reduction of total harmonic distortion in power inverters
(Planta Piloto de Ingeniería Química, 2005-12)
The output voltage of PWM power inverters shows harmonic distortion due to several causes; the main ones are the modulation algorithm, nonlinearities in the output filter, dead times, voltage drops across the switches and ...

Inverter-Side Current Control of Grid-Connected Voltage Source Inverters With LCL Filter Based on Generalized Predictive Control
(Institute of Electrical and Electronics Engineers Inc., 2018-12-12)
In this paper, an inverter-side current (ISC) control strategy for grid-connected voltage source inverter with LCL filters is proposed based on a generalized predictive control (GPC) formulation as it has the advantages ...
Resonant current controller with enhanced transient response for grid-tied inverters
(Institute of Electrical and Electronics Engineers, 2018-04-08)
This paper highlights the limitations of the dynamic response of a grid-tied inverter connected through an inductor $L$ when it is controlled using a proportional+resonant controller. Then, a new resonant current controller ...

Complex-based controller for a three-phase inverter with an LCL filter connected to unbalanced grids
(Institute of Electrical and Electronics Engineers, 2019-04)
A new controller for a grid-connected inverter with an LCL filter is proposed in this paper. The system is described by its complex representation, and the controller is designed using the complex root locus method. The ...
Digital Control of a Three-Phase Four-Leg Inverter to Feeds Non-Linear Loads
(Institute of Electrical and Electronics Engineers, 2021-05)
This paper presents a new control strategy for three-phase four-leg inverters, to meet the requirements of total and individual harmonic content imposed by IEC 61000-2-2 when the inverter feeds a non-linear reference load ...
Fault diagnosis in grid-connected PV NPC inverters by a model-based and data processing combined approach
(IET, 2019-10)
This paper presents a fault detection and isolation (FDI) method for open-circuit faults (OCF) in the switching devices of a grid-connected neutral-point-clamped (NPC) inverter for photovoltaic (PV) applications. The ...
The Poincaré half-space of a C∗-algebra
(Universidad Autónoma de Madrid, 2019-08)
Let A be a unital C*-algebra. Given a faithful representation A⊂B(L) in a Hilbert space L, the set G^+⊂A of positive invertible elements can be thought of as the set of inner products in L, related to A, which are equivalent ...
LPV Control of Current Source Inverter synchronized with the grid
(Institute of Electrical and Electronics Engineers, 2020-10)
Power inverters are widely used in grid connected applications, specially with the increasing use of renewable energies, to improve power quality and increase efficiency. However some parameter associated to the grid and/or ...
